Bed is firm. Bed fit queen frame. Nice delivery. Good for shoulder pain. Me and my fiancé both sleep in this bed and have no complaints of bed sinking in as I have read from other consumer reviews. I am 165 lbs and my fiancé is 175 Ibs. Bed sits high. We had a memory foam bed and switched to this bed it's very different. I feel my body moves less during the night and wakes up in less pain form this bed as compared to the memory foam.  Memory foam allows your body to press in where this bed the Beauty Rest does not, your body will rest on top not sink in. This is coming from our body weight, heavier people may experience different results.  Use a pillow for neck, it's that firm. We are happy with our purchase. Thank you Wayfair. FIRM.
